'tige stimule' rifarsi tu inviten lintera 'Btteut mit mating tutti, fije amt l Be itknown that I, RADCLIFFE yB. LOCKWOOD, of the cityand county andState of New York, have invented a certainnewandusefulmethod of Disinfecting ,and Deodorizing the Noxious Gases or vapors generated in Rendering Houses, Hospital Buildings, or Sewers.; and I do hereby declare the Vfollowing to beI a full,"clcar,

and exact description of the same, reference being had to the annexed drawing, making part of this specification, A in rfhich v i i Figure 1 shows an 'elevation of a building with my invention applied thereto; and

. Figure 2 shows a ground plan of said building with said invention applied as aforesaid.` t

In rendering or slaughtering houses, hospitals, and buildings used for similar purposes, there are always `more or `less noxious and offensive gases or vapors generated, which is allowed to escape inthe open atmosphere,l `making the `neighborhood of such establishment unhealthy and the establishment itself `anuisance. To furnish Y a` meansof controlling, disinfecting,.and deodorizing or consuming the gases as they escape from buildings of this kind, as well as sewers, is the object of this invention, which object Ilaccomplish in the following manner, that` is to say, I commence by making the building or house to be used for the businessor purposeaforesaid, oreithor 4oi them, as nearly tight as possible, so as to exclude the air from entering at-any point exceptingithose especially j `provided for that purpose, by which means I can control the admission of fresh air'to the building. Ithen arrange h inconnection with.' theupper loart of thc building or room used for the business or purpose aforesaidolie' or more openings of suiiicient capacity to take oil all the air admitted thereto, together with all ,the gas and vapors generated therein; by-these means Iam enabled to control the escape of the gases, air, orvapor from the room or` building. l-Iaviug thus provided a means of controlling the admission of the air and the escape of the aii, noxio,us gases,`and vapors, I next provide a means of dcodorizing or disinfecting the said gases, which can only be done by dis-organizing them either thrbugh the agency of intense heat, 'or by the use of chemical agents. To cti'ectthe disorganiaationl or consumption of the gases through the agency of heat, I arrange in` connection with the opening or openings aforesaid, in connection withthe top of the building or room, a fan blowenorair pump -o`r some similar apparatus, which will draw the gases and air out of the room or building,` and force it thro'ugh a.

coil or pipe arranged over a furnace and` s o as to deliver into the iire, by Vwhich the gas and air is rst superheated and then consumed. ,To disorganize these gases by theusc of` chemical agents I propose te blow or force them from the room or building, through a chamber filled with some good disinfctantor deodori'zing agent, such as cholordo of lime; for example, by means of' pumps or blowers, arranged in connection with `the Yescape opening the same as when the air is forcedthrough thesuperheater.

The idea intended to be embodied by my invention, is controlling the admission of the air to the room or building used i'or the purpose aforesaid, and so controlling and treating the escaping airor gases or vapors, as

to disinfect and deodorize them on their passage from the building to the atmosphere outside. The means,

, apparatus or contrivance, by which I have reduced this idea to practisc,lis shownl in the drawing hereunto annexed. This drawingreliresents a square building fitted with'a receiving room, H, inrvhich a horse and cart burdened with dead animals or other oifal may be driven; thisroom or chamber is provided with thedoors, 1.' c, both of' which closo tight enough to practically exclude the atmosphere;` the door, c,'bcing first opened` to admit the horse and cart is closed after it, the door, t', is then openedand the team allowed to enter the building,`

by this means little or no gas can escape through the doel' from the building, and not suihcient air will be admitted to disturb the general atmosphere inside thereof. The windows, wall, and roof ofthe building are also made practically air-tight, excepting the fines, e c, made through the `Wall near the bottom `to admit the air for ventillation. These ilues arc fitted with valves or covers, N, which valves are attached to levers suspended on pivots, Hset in the wall, the top of said levers being connected to the rod, D,`l1y` which a number of said.

' valves can bc opened or closed at once by moving said rod one way or the other' `asthc case may require.

These lues and valves are to regulate the admission of air to thebuilding, and their., number may'be'increascd nr diminished so as to supply what air` may bo neeessaryto thoroughly ventilato thc building in ease it can bo thoroughly ventilated through lues made in the side walls.' Butin case the building is solange, and the draught l e 3 il towards the top thereof, induced Et'heblcweir, A, crries the oir admitted through these iiues upvnear the wall without disturbing th atmosphere 1h the centre of .the building, it will be necessary to run one or more lucs, F, all the way across the iioor of the huilding, communicating with the out sidc of the wall. This lue should be made in the form of a triangle'with holes cut in the ftwo upper sides ns sho'wn by the arrows in iig. andby dottedliues in g. 2, nndoverthis Bue there should he arranged and secured-e. deiiector as shown in iig. 3, so as to distribute the air-through the building. Theopeningsinthe end of thsue should 'also be tted with valves to regulate the admissicnof air thereto,lthe same'asin the case of the other iues. The blower for drawing the nir out of the building-and forcing. it through the'gsuperheater vand/into the 1i re,is shown by A, and is in this case ar'rnngedonthetop of tliebhifding, whereit is 4covered by n. house, K. i The blower delivers the air and gas inten coil of pipeiitted intoachamberfR-i and arrangedover a furnace inthe manner shown, and is so constructedas to terminateunde'rthe 'ffn'rnaceand' deliver. the gasesV either under the grate bni's of the furnece, or over the irethrough brancirf-pipe, Vina-the manner shown. For this blower, A, there may be substituted au air pump, tofoi'oer the airthrough4 the tsuperheater, and fire, or a tall chimney may be used to insure sufficient draught-todiw-'theL air,-.g'as`es,nd vapors through the superheater and fire; but whether one f or the other of thesev devices be `nppiied, thepractise will be substantially the same, and will fall within the scope of 'my invention. and patent, which I' do not intend to confine to any particular 'make of apparatus, but-in which I'x'neai-to include every variety of .apparatus or methodv which is in substance the same as herein described. v

In lapplyingthis invention to sewers, they (the sewers) `should be made to deliver their noxious gases into.

a. closed building or chamber to which the disinfectin'g and deodorizing appamtusl may be applied and operated the same as shown iu' the drawing. It'will of course be understood that in the practise of this invention in cese a. blower or pump be used instead of a chimney, steam or other` convenient power'is to be employedfto drive the pump or blower 4as the 4case may be. v

Having ynow described the nature of lmy Ainvention and the manner of practising the same, I. claim sind desire tosecure by 'Letters Patent- Controlling,disinfeeting, anddeodorizing thenoxious gases or'vapors generated in renderinghouses,`

slaughter houses, hospitals, or' sewers, by forcing or drawing said gas or vapors from said building, houses or sewers, through a superhating or other furnace or through a chamber charged wiith a. disinfecting and deodorizing material, by whichsaid lgases or vapors are disorganized and rendered innoxious'andinodorous or are consumed.
